### Set Operations and Venn Diagrams

#### Problem Statement

Given the sets:
\[ A = \{ m, 4, 2, 13 \} \]
\[ B = \{ 1, 2, 4, 13, -2 \} \]
\[ C = \{ 1, 3, 5, 7, 9 \} \]

We need to find the following:

1. \( A \cup B \)
2. \( A \cap C \)
3. \( (A \cup C) \cap B \)

### 1. Finding \( A \cup B \) (Union of Sets \( A \) and \( B \))

The union of two sets \( A \) and \( B \) includes all elements from both sets, without duplication.

\[ A \cup B = \{ m, 4, 2, 13 \} \cup \{ 1, 2, 4, 13, -2 \} \]

Steps:
- List all unique elements from both sets.
- Combine the lists, removing any duplicates.

Result:
\[ A \cup B = \{ m, 4, 2, 13, 1, -2 \} \]

### 2. Finding \( A \cap C \) (Intersection of Sets \( A \) and \( C \))

The intersection of sets \( A \) and \( C \) includes only those elements that are present in both sets.

\[ A \cap C = \{ m, 4, 2, 13 \} \cap \{ 1, 3, 5, 7, 9 \} \]

Steps:
- List elements that appear in both sets.

Since there are no common elements between sets \( A \) and \( C \):

Result:
\[ A \cap C = \emptyset \] (or equivalently, \( \{ \} \))

### 3. Finding \( (A \cup C) \cap B \)

First, calculate \( A \cup C \):

\[ A \cup C = \{ m, 4, 2, 13 \} \cup \{ 1, 3, 5, 7, 9 \} \]

Result:
\[ A \cup C = \{ m, 4, 2, 13, 1,
